useful Improvement in Corrugated-Metal Car Ends, and declare the following to be a full, clear, and exact description of the same, such as will, enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form apart of this spec-licatio'n.

My invention has for its object. to produce a sheet metal panel which will possess a much greater strength to resist forces acting transversely to the plane thereof than do any sheets or panels of which I am a'ware.

It' is known that the corrugating of a metal sheet greatly stiflens it. When subjecting a corrugated sheet to pressure at right. angles'to its plane, the initial resistance is not nearly as great as it is after a considerable distortion orI bowing of the corrugations has taken place. In accordance with my invention, I so construct Ythe corrugations that they are normally bowed lengthwise in planes at right angles to the plane of the sheet, thus securing the advantage of the greater strength of such corrugations at the very instant of the application of a load.

My invention is particularly applicable to railway car construction,l especially in the manufacture of metal ends and therefore, viewed in oneof its as ects, my invention may be said to have for its object to produce f a simple, strong sheet metal panel adapted for use in the construction of walls, particularly ends, of railway cars. Y Y

The various features of novelty whereby mfy invention is characterized will hereina ter be 'pointed out with particularity -in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had t0 the following vdetailed description taken in connection with the accompanying drawings, wherein:

Fig.13 is a sectionltaken approximately on line 13--13 of Fig. 11. l

In Figures 1 to 3 of the drawings I -have illustrated my invention in the form of an end for a box car, the end being made in twopanels one arranged above the other. Referring to these figures, 1 and 2 represent respectively the lower and the upper panels, these belng conveniently secured together by a riveted lap joint 3. Each of the panels is in the form of a Hat sheet having a pluralityof parallel corrugations extending from the vicinity of one side edge to the vicinity of the other side edge. In the particular arrangement shown, each entire panel, with-the exce tion of a flat marginal rim-like portion is lled with corrugations, the latter being' of approximately uniform depth throughout their length.

' In accordance with my invention I bend the corrugations lengthwise transversely of the plane vof the sheet without bodily bend-'l ing the sheet so as to give them an arched or bow-shaped formation. This can be accomplished, without unduly deepening the corrugations, by pressing a portion ofeach corrugation in one direction from the plane ofthe sheet' andV the remainder of the corrugation xin the' oppositefdirection from said "plane, sov that each corrugation lies partly on `one side of the sheet and partly on the other.

undue stretching of the metal in making the flanged around the same as indicatedl at 10.v a Secured to the inner faces of the posts are corrugations is avoided. In the arrangement shown, the central section, 4, of each corrugation is pressed outwardly from the plane of the sheet while the two end sections, 5 and 6, are pressed inwardly, all three of the sections being preferably straight. T he extreme ends of the corrugations are preferably flattened as indicated at 7, so as to lie in planes which make an obtuse angle with the plane of the sheet. The metal end is fastened to the sides, 8, of the car in any suitable way. The ends are illustrated as terminating in corner posts, 9.l The flat marginal portions at the sides of the end extendV across the posts and are vertical reinforcing bars, 11,l L-shaped in cross section, one flange of each of these bars being conveniently tied to the post and to the ange, 10, by means of bolts, 12, and the other flange being fastened to the end sec-l tions, 5 of the corrugations by suitable rivets, 13. Further stiffness may be given to each corner by means of an angle iron, 14, one lange of which is riveted to the member 11 as indicated at 15, and the other of which is bolted through the corresponding side of the car and through the corresponding liange, 10, by means of bolts, 16.

lin e the corrugations are shown as being somewhat longer than in Figs. 1. to 3, the flattened ends of the end sections resting against a correspondingly-shaped surface, 17, on thepost 18. ln addition to the bolts, 19, passing throughv the post and i the flange 10, there are other bolts, 20, ex-

- central sections tending through the post and the flat marginal portion'of the sheet parallel with the longitudinal axis of the car. reinforcing bar, 21, l..shaped in cross section, is secured by one iiange to the post by means of the bolts, 19, and has its other flange riveted to the corrugations as indicated at 22.

ln Figs. 5 and 6 there is shown a bon car in which the end is made up of three panels, 23, 24 and 25, similar to those heretofore described except that the central sections, 26, of the corrugations are pressed inwardly from the plane of the sheet while the end sections, 27, are pressed outwardly. The entire end is stiilened and reinforced by means of vertical posts or bars, 28, which may conveniently be Z-bars, extending vertically across the endend at the angles between the of the corrugations and the end sections. The side marginal portions are anged aroundthe posts 9 as in the construction shown in Fig. 3. Further security of attachment to the sides of the car is secured by means of straps, 29, extending along the' inner walls of the car sidesl and having their ends secured by means of rivineogee ets, 30, to the inner faces of the llattened ends, 7 of the corrugations. rlhe bolts 12 which pass through the post and the ilange 10 also pass through the straps so as to tie the three together.

In F ig. 7 there is illustrated an end similar to that shown in Figs. 5 and 6, applied to a car having 'thin sides that do not terminate in corner posts. The fiat marginal portions at the sides of the end are bent inwardly, as indicated at 31, across the inner walls of the sides, 32, of the oar. At each corner is a vertical reinforcing bar having onel section or flange, 33, secured to the flattened ends, 7, of the corrugations by rivets, 34; a web, 35, engaging with the extreme end of the car side, and a second ange, 36,

overlying the outer face or surface of' the n, car side. Bolts, 37 pass through the tlanges i 36 and 31 and through the car side so as to tie these three elements together. Further reinforcement of the corner may be secured by means of straps, 38, extending from the corner inwardly or rearwardly to one of the vertical stanchions or posts, 39, that are usually placed along the .outside of thin side walls of the kind illustrated; one end of' each of the straps being lsecured in place `as heretofore explained, and the corners are relnforce'd `by means of the l..shaped bars,

11, and the angle irons, 14, cdrresponding to the parts similarly numbered in Fig. 3. Around the top of the car is a bulb angle, el, one l'ange of which is horizontal and one flan e of which is vertical and arranged behin the upper dat marginal portion of the panel, the panel and this vertical ange being fastened together by rivets, 42. The

panel is Banged outwardly at its lower end as indicated at i3 and is riveted to the upper flange of the end sill, 44, or other suitable floor structure.

ln Figs: 11 to 13 l have illustrated panels having additional reinforcing means, the,

panels being shown as applied side by side to torni the end of a box car, and the corru-l gations in the panels extending vertically. Referring to these Figures, 51, 50-and 52 represent respectively a central and two side panels which, together, form a complete end.

The panels are fastened to ether in any suitable way as, for examp e, by v means of riveted lap yoints, 53. rl`he corrugations in this form of my invention are vertical, each corrugation comprising a central section,54, pressed inwardly from the plane of the sheet and upper4 `and lowerfsections, 55` and 56, pressedoutwardly. The extreme upper and lower'v ends ofv the corrugations are flattened, as indicated at 7, in the same way as in the otherforms of the invention illustrated. The marginal side portions of the 'end are flanged, as indicated at57, sov as to overlie the outer faces of the'sides, 58, of the car body. If desired, reinforcing bars, 59, and 60, may extend transversely across the end at the angles between the central and end sections of the corrugations. The stresses from these reinforcing bars may be inpart transferred to the sides of thecar body by means of suitable straps, 61, extending along the sides of the car on the exterior thereof and bent laterally at their outer ends, as indicated at 62, so as to overlie portions of the reinforcing bar's 59 and 60; the'part 62 being riveted or'otherwise secured to these bars, conveniently by means of rivets, 63, passing through the salne, through the bars, and through the metal ends and, if desired, by means of additional bolts, 64;, passing only through the member 62 and the reinforcing bars.

Across the attened upper ends of the corrugations, and secured to such flattened ends by rivets or other suitable means, is a plate,

65. A similar plate, 66, extends across and is secured to the iattened portions at the extreme lower ends of the eorrugations. Between the plates 65 and 66 extend one or more ties oritension members; there being shown three such members, 67, 68 and 69, the member 67 extending across the longitudinal center-line of the central panel and the other two members being located at the middle of the other two panels. These ties or tension members constitute the strings to the bows formed by the bent corrugations and, when pressure on the inner side ofthemetal end tends to straighten the corrugations, this action will be resisted by the tension members.

The lower ends of the intermediate reinforcing bars, where vertical reinforcing bars areemployed as illustrated at 28 in Fig. 5, may be secured to the end sill, 70, or other part of the car floor frame by suitable fastenin'g means 71. i

While l have illustrated and described with particularity only a few preferred.

forms of my invention, l do not desire to be limited to the particular details thus illustrated and described; but intend to cover all forms and arrangements coming within the definitions of my invention constituting the appended claims. Furthermore, l desire to have it understood that the word bent is used in thelfclaims moreJin the sense of shape or contour rather than in the sense of a particular processeinployed in-producing such shape. f Inf-other words,by\fbent I mean somethingthat is not straight.
